CARfCOUPLING.

SPECIFICATION forming part of Letters Patent No. 484,451, dated October18, 1892.

Application iiledMarch 5, 1892. Serial No. 423.955. (No model.)

To all whom it may concern:

Be it known that I, EDWARD W. PAERow, of Plymouth, in the county ofPlymouth and State of Massachusetts, have invented a new and usefulImprovement for Coupling and Releasing Cars, of which the following,taken in connection with the accompanying drawings, is a specification.

The object of my invention is to produce a coupling for car,particularly applicable to freight-cars, whereby the cars will beconnected automatically as their respective drawheads approach or comeinto contact with each other and which canreadily be released bydepressing a bar on the side of the car, as hereinafter fully described,and pointed out in the claims.

Referring to the accompanying drawings, Figure l represents a verticalsection through a car-coupling embodying my invention as applied to theend of a car. Fig. 2 is a front View of the same.

A represents a portion of one end of a car, B the draw-head, the rearend of which is fulcrumed at c to a beam C, secured transversely to theunder side of the car, so that the forward end of the draw-head is freeto move laterally for a short distance, the amount of its travel beinglimited by a saddle D, secured to the car. The draw-head B is hollow forthe greater portion of its length and is formed with an opening b in itsunder side and an opening b in its upper side, in which is iitted alever E, fulcrumed at e to two ears on the top of the draw-head.

Secured to or formed in one with the forward end of the lever E is afurcated piece F, the prongs of which are each formed with a slot f,thecoupling-pin G passing through the prongs and secured thereto by a ping. The coupling-pin passes down through holes in the draw-head, asshown. To the rear of the lever E is secured a chainV H, the Llower endof which is connected to an arm I, secured to a rocking shaft J, thatextends eutirely across the car and is carried by bearings K, secured tothe under side of the car. On each end of the rocking shaft J is securedan arm L, to which a vertical rod M is secured. This rod passes up tothe top of the car and is bent over to form a handle, as at m, so thatit can be operated from the top of the car.

These rods are held up in their normal position by spiral springs N,interposed between a bearing n, secured to the side of the car, and apinn, passing through the rod M. The inner portion or mouth of thedraw-head is formed with a wedge-shaped piece or guide P on each sidethat supports and upon which slides a block Q, from the rear of whicheX- tends a rod q, the end of which passes through a bar B', formed inone with the draw-head. A spiral spring R is interposed between theblock Q and the bar B', to keep the block pushed forward, a small pin qcoming into contact with the bar B prevents its being pushed beyond therequired distance. The object of this block is to support thecoupling-pin G when the car is not connected to another car. Thiscoupling is to be used with the ordinary connecting-link.

The operation is as follows: Supposing the coupling to be in theposition shown in dotted lines in Fig. l-that is to say, after the bar Mhas been depressed and the forward end of the lever E raised and thecouplingpin G resting upon the top of the block Q, which is pressedforward by the spring R- noW if another car carrying a coupling-linkapproach the car the end of the link will strike the block Q and push itback and the coupling-pin G will be free to fall, thus connecting thetwo cars. To again uncouple the cars, all that has to be done is todepress the bar M, which causes the arms L and the rocking shaft .l toturn, and with them the arm I, which draws down the chain H and therebythe outer end of the lever E, raising its forward end and with it thecoupling-pin G, which when raised allows vthe block Q to be pressedforward and under it by the spring R until the car is again coupled toanother.

What I claim as my invention isl. In a car-coupling, a draw-headfulcrumed to the car at its rear end and having a lever on its upperside fulcrumed4 as described, a chain and arm for connecting its rearend to a rocking shaft, arms secured to the ends of said shaft, rodsattached to said arms, and spiral springs for keeping the rods in theirnormal position, in combination with a coupling-pin and a block forretaining same in place when raised, said block being operated by aspring, substantially as set forth.
